Odds API by market / NCAAB
NCAAB Point Spread API
Live spreads odds across every book that posts it, in one REST call — and, unlike any other odds API, every one of those outcomes settled against the official result once play ends.
No credit card. 1,000 requests / day on the free tier.
What NCAAB point spread is
The handicap market. Each outcome carries a `point` (the handicap) alongside its price. Alternate spreads arrive in the same response rather than behind a separate paid market, so a full ladder is one request.
How we settle it. Settled against the final margin. An exact push on a whole-number handicap returns `push`, not a win or a loss.
Every number on this page is measured against the live API, never copied from a spec sheet. Last measured 14 November 2026.
Books posting NCAAB point spread
Measured live, not listed from a spec. Coverage moves — a book that has not put its board up yet will not appear until it does, which is exactly what this list is for.
Line shopping across all of them is one request — every book arrives in the same bookmakers array, not one call per book. Add ?bookmakers= to narrow it, or use /best-line for the best price per line already ranked.
Recently settled NCAAB point spread outcomes
These are real rows out of the API, not an illustration. Each one was a price on a board before the event and carries the actual figure it was graded against afterwards. No other odds API returns that last column — they stop at the price.

Hit rate, last 4 days
49.1% of 107981 settled point spread legs hit (53065 yes, 54916 no). Counted on the YES side only — books that price this two-way contribute their Over leg, not both. That is the base rate across the whole priced field, not a per-player figure.
Read off 107,981 YES legs out of 108,506 settled outcomes on this market. The rest are the Under side from books that price it two-way, which answers a different question.
Per-player hit rates and L5 / L10 / L20 splits live on /trends.
Live response
Captured from the real endpoint on UNC Greensboro @ Cornell, trimmed to one book and three outcomes so the shape stays readable. The full response carries every book and every line, alternates included, in the same call.
